‘Earliglow’ ‘Flavorfest’ Anthracnose-resistant ‘Allstar’ ‘Ovation’
Plugs are made from end of June to 4 July. • Plugs are planted in the field the first half of August. • The field is fertigated with ~12lbs/A of nitrogen after one • week, every week to 3rd week of September, to a total of ~75 lbs/A. • The beds are covered with straw mid-December to mid- • March.
Influence of Nitrogen, Phosphorus, and Potassium on the Severity of Strawberry Anthracnose Crown Rot • B.J. Smith • United States Department of Agriculture, Agricultural Research Service • Southern Horticultural Laboratory, Small Fruit Research Unit • Poplarville, MS 39470 • USA • Seven (7) nitrogen sources at three (3) rates: • Higher N rates led to more anthracnose. • Among plants getting higher N rates, those treated with • Ca(NO3)2were the most disease tolerant. • Plants treated with nitrate nitrogen sources, including • NH4NO3, had less severe anthracnose symptoms than • plants receiving nitrogen from other ammonium sources. • Take-home: Nitrate forms mean less anthracnose than ammonium forms.
Frost protection is a combination of misters at 34F and Rainbirds at 32.1F. • The field is fertigated with ~5lbs/A of nitrogen per week in April, to between 20-30 lbs/A. • Plots are harvested twice weekly from mid-May through mid-June. • Rotation is ‘Essex’ rape - strawberry – corn or sudex – soybeans, with rye-vetch winter covers.
